Nginx + PHP5-FPM repeated cut outs 502
- by James
I've seen a number of questions here that highlight random 502 (Nginx + PHP-FPM = "Random" 502 Bad Gateway) and similar time outs when using Nginx + PHP-FPM.
Even with all the questions, I'm still unable to find a solution.
Using Ubuntu 10.10 + Nginx + PHP5-FPM + APC and every 1 out of 4 requests ends in a timeout and failure. This isn't a load issue or large traffic, it happens even in dev environment with one person.
I am doing this across 3 1GB machines, each with the same configurations and same problems.
